This short paper discusses a case study of multi cluster visualization of Static Analysis Security Testing (SAST) warnings in large clusters catering to a majority of Cisco products in hierarchical organizational and checker views. This serves as a one stop shop for real-time visualization of Static Analysis (SA) warning trends, chart, downloading reports, and to effectively address the potential security weaknesses detected. Presently leading SAST tools like Coverity, codesonar, Klocwork etc do not provide inter-cluster or enterprise-wide visualization to effectively address the SA warnings.

This paper presents a novel augmented reality (AR) interactive environment for neurosurgical training. Comparing with traditional virtual reality based neurosurgical simulator, our system provides a more natural and intuitive fashion for surgeons. To achieve holographic visualization of virtual brain on 3D-printed skull (workspace), the first step is to reconstruct the personalized anatomy structure from segmented MR imaging. Then, tailored to the computational power of HoloLens, we employ the mass-spring method to model the mechanical response of brain. After that, a precise registration method is employed to map the virtual-real spatial information, which can overlay the virtual operative brain on workspace. In addition, bimanual haptic interface is also integrated into our simulator, which is more similar with real neurosurgery. In experiments, we conduct accuracy validation on our registration method, as well as the validity test on the developed simulators. The results demonstrate that our simulator can provide high-accuracy augmented visualization effects and deep immersion for novice surgeons.

The Virtual eXperiences Lab at RMIT is a "21st century lab scope," an enabling platform for research and prototyping in industrial automation, focusing on software engineering, next generation human-machine interaction experiences, user interfaces, and training. VxLab combines high resolution visualization, industrial automation facilities and cloud-based simulation servers in a dedicated private network. In this paper we describe the architecture, use cases, and research and innovation projects. We also present experiences applying VxLab. We present capabilities, include connected infrastructure provided by industry partners.

This study examines the performance of stocks investment portfolio by using accounting information. The sample is selected from Taiwan Economic Journal to test F-SCORE cooperating with Dividend-to price ratio, Earnings-to -price Ratio and Book-to -Market respectively. The sample period is from May, 2008 to May, 2018. The findings of this study are as follows. First, if we choose Dividend-to-price ratio, Earnings-to -price Ratio or Book-to-Market to distinguish from the value and growth portfolio, the value portfolio is significantly better than the growth one. Second, if we choose F-SCORE to distinguish from high and low score, the high score portfolio is significantly better than the low score one. The result showed that when the investor use Dividend-to price ratio, Earnings-to-price Ratio or Book-to-Market together with fundamental financial information, they could become more profitable or more effectively improve the performance.

Wireless Sensor Networks (WSNs) are rapidly gaining popularity in various critical domains like health care, critical infrastructure, and climate monitoring, where application builders have diversified development needs. Independent of the functionalities provided by the WSN applications, many of the developers use visualization, simulation, and programming tools. However, these tools are designed as separate stand-alone applications, which force developers to use multiple tools. This situation often poses confusion and hampers an efficient development experience. To avoid the complexity of using multiple tools, we have designed a new extensible, multi-platform, scalable, and open-source framework called PROVIZ, which is an integrated visualization and programming framework. In this paper, we explain the various features of PROVIZ's visualization and programming framework and discuss how PROVIZ can be used as a visual debugging tool to aid in providing a software fix.

In the virtual hand interaction techniques, the opacity of the virtual hand avatar can potentially obstruct users' visual feedback, leading to detrimental effects on accuracy and cognitive load. Given that the cognitive load is related to gaze movements, our study focuses on analyzing the gaze movements of participants across opaque, transparent, and invisible hand visualizations in order to create a new interaction technique. For our experimental setup, we used a Purdue Pegboard Test with reaching, grasping, transporting, and inserting subtasks. We examined how long and where participants concentrated on these subtasks and, using the findings, introduced a new virtual hand visualization method to increase accuracy. We hope that our results can be used in future virtual reality applications where users have to interact with virtual objects accurately.

The definition of consonance as the ability to resolve a sound into the pitch categories is introduced. For a vector space of chords a norm is used to evaluate the consonance linearly in dependence of the instrument used. It is shown that in the corresponding Hilbert space the chords which usually appear together in a conventional musical piece are recognized in terms of `closeness`.

In this paper, the clustering and visualization capabilities of the SOM, specifically tailored for the analysis of textual data, are reviewed and further developed. A novel clustering and visualization approach is proposed for the task of textual data mining. The proposed approach first transforms the document space into a multi-dimensional vector space by means of citation patterns. An intuitive and effective projection method, namely the Ranked Centroid Projection (RCP), is then applied in conjunction with a dynamic SOM model, the Growing Hierarchical Self-Organizing Map, which automatically produces document maps with various levels of details. The RCP is used both as a data analysis tool as well as a direct interface to the data. We also extend the RCP to address the problem of the incremental clustering of dynamic document collections. In a set of simulations, the proposed approach is applied to a synthetic data set and two real-world scientific document collections, to demonstrate its applicability.

Pipe inspection is a critical activity in gas production facilities and many other industries. In this paper, we contribute a stereo visual odometry system for creating high resolution, sub-millimeter maps of pipe surfaces. Such maps provide both 3D structure and appearance information that can be used for visualization, cross registration with other sensor data, inspection and corrosion detection tasks. We present a range of optical configuration and visual odometry techniques that we use to achieve high accuracy while minimizing specular reflections. We show empirical results from a range of datasets to demonstrate the performance of our approach.
